ADJUSTING THE ELECTRONIC SPEED CONTROL

VXL-3s Battery Settings (Low-Voltage Detection Setting)
The Velineon VXL-3s electronic speed control is equipped with built-in
Low-Voltage Detection. The Low-Voltage Detection circuitry constantly
monitors the battery voltage. When the battery voltage begins to reach the
minimum recommended discharge voltage threshold for LiPo battery packs,
the VXL-3s will limit the power output to 50% throttle. When the battery
voltage attempts to fall below the minimum threshold, the VXL-3s will shut
down all motor output. The LED on the speed control will slowly blink red,
indicating a low voltage shutdown. The VXL-3s will stay in this mode until a
fully charged battery is connected.
When you turn your model on, the VXL-3s speed control's status LED
will glow green, indicating that Low-Voltage Detection is activated to
prevent over-discharging of LiPo batteries. LiPo batteries are intended
only for the most advanced users that are educated on the risks
associated with LiPo battery use.
WARNING: FIRE HAZARD!
Do not use LiPo batteries in this vehicle with
Low-Voltage Detection disabled.
Verify that Low-Voltage Detection is ACTIVATED:
1. Turn on the transmitter (with the throttle at neutral).
2. Connect a fully charged battery pack to the VXL-3s.
3. Press and release the EZ-Set button to turn the VXL-3s on. If the LED is green,
then the Low-Voltage Detection is ACTIVATED.
If Low-Voltage Detection is disabled:
1. Make sure the LED on the VXL-3s is on and red.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light green. Also, a
"rising" musical tone will be emitted from the motor.
3. Low-Voltage Detection is now ACTIVATED.
For NiMH battery users, follow these steps to disable Low-Voltage Detection
(NiMH setting):
1. Make sure the LED on the VXL-3s is on and green.
2. Press and hold the EZ-Set button for ten seconds.
The LED will turn off and then light red. Also, a
"falling" musical tone will be emitted from the motor.
3. Low-Voltage Detection is now DISABLED.
Transmitter Adjustments for the VXL-3s ESC
Before attempting to program your VXL-3s ESC, it is important to make sure that
your transmitter is properly adjusted (set back to the factory defaults). Otherwise,
you may not get the best performance from your speed control.
The transmitter should be adjusted as follows:
If the transmitter setting have been adjusted, reset them to the factory defaults.
1. Turn transmitter off.
2. Hold both MENU and SET.
3. Turn transmitter on.
4. Release MENU and SET. The transmitter LED will blink red.
5. Press MENU once. The transmitter LED will blink red twice repeatedly.
6. Press SET to clear settings. The LED will turn solid green and the transmitter is
restored to default.
VXL-3s Setup Programming (Calibrating your ESC and transmitter)
Read through all of the programming steps before you begin. If you get lost
during programming or receive unexpected results, simply
unplug the battery, wait a few seconds, plug the battery back
in, and start over.
1. Connect a fully charged battery pack to the VXL-3s.
2. Turn on the transmitter (with the throttle at
neutral).
3. Press and hold the EZ-Set button (A). The LED will
first turn green and then red. Release the EZ-Set
button.
4. When the LED blinks RED ONCE, pull the throttle
trigger to the full throttle position and hold it there
(B).
5. When the LED blinks RED TWICE, push the throttle
trigger to the full reverse and hold it there (C).
6. When the LED blinks GREEN ONCE, programming is
complete. The LED will then shine green or red (depending
on low-voltage detection setting) indicating the VXL-3s is on
and at neutral (D).
VXL-3s Operation
To operate the speed control and test programming, place the vehicle on
a stable block or stand so that all of the driven wheels are off the ground.
Disconnect motor wires "A" and "C" (see page 14), this will assure the motor
does not drive the wheels during testing. Do not test programming without
disconnecting the motor wires.
Note that in steps 1-7 below, Low-Voltage Detection is ACTIVATED (factory default)
and the LED shines green. If Low-Voltage Detection is DISABLED, the LED will shine
red instead of green in steps 1-7 below. Never use LiPo batteries while Low-Voltage
Detection is disabled.
1. With the transmitter on, press and release the EZ-Set button. The LED will
shine green. This turns the VXL-3s on.
2. Apply forward throttle. The LED will turn off until full throttle power is reached.
At full throttle, the LED will illuminate green.
3. Move the trigger forward to apply the brakes. Note that braking control is fully
proportional. The LED will turn off until full braking power is reached. At full
brakes, the LED will illuminate green.
4. Return the throttle trigger to neutral. The LED will shine green.
5. Move the throttle trigger forward again to engage reverse (Profile #1). The LED
will turn off. Once full reverse power is reached, the LED will illuminate green.
6. To stop, return the throttle trigger to neutral. Note that there is programmed
delay when changing from reverse to forward. This prevents damage to the
transmission on high-traction surfaces.
7. To turn the VXL-3s off, press the EZ-Set button until the LED turns off (.5 seconds).
